1、总览
2、代码
1）、pom.xml
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies>
2）、MyController.java
package com.ebc.controller; import com.ebc.error.NotYetImplemented; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class MyController { /** * response status code=500，导航到5xx.html */ @RequestMapping("/") public void handleRequest() { throw new RuntimeException("test exception"); } /** * response status code=501，导航到5xx.html */ @RequestMapping("/app") public void handleAppInfoRequest() throws NotYetImplemented { throw new NotYetImplemented("The request page is not yet implemented"); } }
3）、ForbiddenException.java
package com.ebc.error; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ResponseStatus; @ResponseStatus(HttpStatus.FORBIDDEN) public class ForbiddenException extends Exception { public ForbiddenException(String message) { super(message); } }
4）、NotYetImplemented.java
package com.ebc.error; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ResponseStatus; @ResponseStatus(HttpStatus.NOT_IMPLEMENTED) public class NotYetImplemented extends Exception { public NotYetImplemented(String message) { super(message); } }
5）、5xx.html
<html> <body> <h1>My 5xx Error Page</h1> <div id="locationDiv"></div> <script> document.getElementById("locationDiv").innerHTML = "Location: " + window.location.href; </script> </body> </html>
6）、404.html
<html> <body> <h1>My 404 Error Page</h1> <div id="locationDiv"></div> <script> document.getElementById("locationDiv").innerHTML = "Location: " + window.location.href; </script></body> </html>
3、执行
总结：
1、如果出现了非5xx、404返回码如403时，怎么办？使用error.jsp，并将其放在根下，如本例需放在static目录下。
2、5xx.html、404.html需放在error目录下。
